Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 135 words
A plug-in ceramic package for an electronic component comprising a ceramic base having upper and lower surfaces and comprising a plug-in part and a component-holDing part, said component-holding part having a cavity for receiving an electronic component containing a plurality of metallic terminals for connection to said electronic component, means surrounding said cavity for attaching a cover over said cavity, said plug-in part having a plurality of spaced-apart, relative narrow, exposed parallel metallic contact surfaces adherent to at least one of said upper and lower surfaces of said ceramic base and running from the edge of said plug-in part toward the cavity of said component-holding part, and, metallic leads at least partially buried within said componentholding part of said ceramic base electrically connecting the metallic terminals in said cavity with said parallel metallic contact surfaces.
Claim 2
Dependent Claim 135 words
A plug-in ceramic package for an electronic component comprising a ceramic base having upper and lower surfaces and comprising a plug-in part and a component-holDing part, said component-holding part having a cavity for receiving an electronic component containing a plurality of metallic terminals for connection to said electronic component, means surrounding said cavity for attaching a cover over said cavity, said plug-in part having a plurality of spaced-apart, relative narrow, exposed parallel metallic contact surfaces adherent to at least one of said upper and lower surfaces of said ceramic base and running from the edge of said plug-in part toward the cavity of said component-holding part, and, metallic leads at least partially buried within said componentholding part of said ceramic base electrically connecting the metallic terminals in said cavity with said parallel metallic contact surfaces.
Claim 3
Dependent Claim 140 words
A plug-in ceramic package for an electronic component comprising a ceramic base having a surface comprising two planes, the lower plane forming a plug-in part and the upper forming a component-holding part, said component-holding part having a pad for attachment of an electronic component and having a plurality of metallic terminals for connection to said electronic component, means surrounding said pad and said metallic terminals for attaching a cover thereover, said plug-in part having a plurality of spaced apart, relatively narrow, exposed parallel metallic contact surfaces adherent to at least one of said upper and lower surfaces of said ceramic base and running from the edge of said plug-in part toward said component-holding part, and, metallic leads at least partially buried within said component-holding part of said ceramic base electrically connecting said metallic terminals with said parallel metallic contact surfaces.
Claim 4
Dependent Claim 140 words
A plug-in ceramic package for an electronic component comprising a ceramic base having a surface comprising two planes, the lower plane forming a plug-in part and the upper forming a component-holding part, said component-holding part having a pad for attachment of an electronic component and having a plurality of metallic terminals for connection to said electronic component, means surrounding said pad and said metallic terminals for attaching a cover thereover, said plug-in part having a plurality of spaced apart, relatively narrow, exposed parallel metallic contact surfaces adherent to at least one of said upper and lower surfaces of said ceramic base and running from the edge of said plug-in part toward said component-holding part, and, metallic leads at least partially buried within said component-holding part of said ceramic base electrically connecting said metallic terminals with said parallel metallic contact surfaces.
Claim 5
Dependent Claim 187 words
An integral plug-in ceramic package for an electronic component having a thinner plug-in part and a thicker component-holding part and comprising, a ceramic base having upper and lower surfaces, at least the upper surface being in two planes, thereby forming a thicker side and a thinner side, and edgewise extensions of said base making said sides respectively broader and narrower, a cavity provided with an opening for access to said cavity on the upper surface of said thicker side containing a pad for receiving an electronic component and containing a plurality of metallic terminals for connection to said electronic component, means on said upper surface surrounding said cavity for attaching a cover over said cavity, a plurality of spaced-apart, relatively narrow, parallel metallic contact surfaces adherent to at least one face of said thinner plug-in side of said ceramic base and running from said thicker component-holding side of said ceramic base to the opposite edge of said thinner side, metallic leads at least partially buried within the thicker side of said ceramic base electrically connecting the metallic terminals in said cavity with said parallel metallic contact surfaces.
Claim 6
Dependent Claim 187 words
An integral plug-in ceramic package for an electronic component having a thinner plug-in part and a thicker component-holding part and comprising, a ceramic base having upper and lower surfaces, at least the upper surface being in two planes, thereby forming a thicker side and a thinner side, and edgewise extensions of said base making said sides respectively broader and narrower, a cavity provided with an opening for access to said cavity on the upper surface of said thicker side containing a pad for receiving an electronic component and containing a plurality of metallic terminals for connection to said electronic component, means on said upper surface surrounding said cavity for attaching a cover over said cavity, a plurality of spaced-apart, relatively narrow, parallel metallic contact surfaces adherent to at least one face of said thinner plug-in side of said ceramic base and running from said thicker component-holding side of said ceramic base to the opposite edge of said thinner side, metallic leads at least partially buried within the thicker side of said ceramic base electrically connecting the metallic terminals in said cavity with said parallel metallic contact surfaces.
Claim 7
Dependent Claim 30 words
An integral plug-in ceramic package according to claim 3 wherein the lower surface is in two planes and includes metallic contact surfaces and leads are buried within the thicker part.
Claim 8
Dependent Claim 15 words
An integral plug-in ceramic package according to claim 3 wherein the ceramic base is alumina.
Claim 9
Dependent Claim 26 words
An integral plug-in ceramic package according to claim 3 wherein metallic contact surfaces, metallic terminals and metallic leads therebetween are tungsten, molybdenum, manganese, platinum or palladium.
Claim 10
Dependent Claim 19 words
An integral plug-in ceramic package according to claim 6 wherein exposed metallic contact surfaces and terminals are gold plated.
